AACN CSC Review Course Session 1 UPDATED Exam Questions and CORRECT Answers 70% - Correct ANSWER- at rest the myocardium extracts ___% of available oxygen 30-35% - Correct ANSWER- normal SvO2 in heart 60-80% - Correct ANSWER- normal SvO2 in body coronary perfusion pressure - Correct ANSWER- DBP - LVEDP > 40 mmHg - Correct ANSWER- normal coronary perfusion pressure

Tx to decrease preload - -Diuretics -Dilators (nitrates, nitroprusside, morphine) Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the AV valves close, just prior to ejection -As preload increases, SV and CO will increase up to a point -Too high of a preload may lead to heart failure -Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities Cardiac output equation - CO = HR x SV Components of str...

A patient admitted with sepsis has a pulmonary artery catheter placed that also measures SvO2. During a routine assessment, the nurse notes that the patient's SvO2 is 56%. The nurse knows that this indicates:oxygen supply is not equal to demand. Which hemodynamic changes are associated with mitral stenosis?Elevated left atrial pressure, pulmonary artery occlusive pressure, and pulmonary artery diastolic pressure; normal left ventricular end-diastolic pressure

(Solved with Rationales) Pass CCRN test bank. Which of the following would be the earliest auscultatory finding in left ventricular failure (LVF)? A. Crackles B. S3 C. Murmur of mitral regurgitation D. Pericardial friction rub B. S3 LVF would be the most subtle because early changes are usually subtle changes. Choose "S3." A patient with a triple-lumen subclavian catheter has been receiving total parenteral nutrition, maintenance fluids, and antibiotics by the catheter. He has ...

One hemodynamic benefit of intra-aortic balloon therapy is: A) Balloon inflation prevents right to left shunt B) Balloon deflation increases coronary artery perfusion C) Balloon inflation optimizes aortic valve performance D) Balloon deflation decreases left ventricular afterload - D) Balloon deflation decreases left ventricular afterload Which of the following hemodynamic profiles would benefit from aggressive fluid administration, pressors and antibiotic therapy? A) RAP 1, PAOP 4, SVR ...

CCRN PASS TEST BANK EXAM WITH QUESTIONS AND WELL VERIFIED ANSWERS [ALREADY GRADED A+] ACTUAL EXAM 100% REAL EXAM!!! A patient with a triple-lumen subclavian catheter has been receiving total parenteral nutrition, maintenance fluids, and antibiotics by the catheter. He has been slightly confused. Suddenly he grasps the catheter and pulls it out. He then complains of shortness of breath, and his pulse oximetry indicates an SpO2 of 84%. How should this patient be positioned? A. Head...

Prophecy General ICU RN A V1 What is cardiac tamponade? Fluid in the pericardial sac causing decreasing preload. This decreases SV and ultimately CO. Effects of Hyper/Hypokalemia and calcemia on EKG Hypokalemia causes U waves Hyperkalemia causes peaked T waves Normal BP? 90-120/60-80 Normal HR? 60-100 bpm Normal CO? 4-8 L/min Normal SVR? 800-1,200 dynes/seconds Normal PVR? 37-250 dynes/sec/cm5 Normal SVo2? 60-80% Normal PAP? Systolic: 15-30 mm Hg Diastolic: 4-12 mm Hg Normal...
